It is a three-chamber system designed for the construction of external doors, windows and various types of glass-cases. Thermal separator (with a width up to 24 mm) used in profiles is made of polyamide enriched by multidirectional oriented fiberglass and it significantly improves the mechanical strength of the inner and outer chambers of the profile. Thermal separator is additionally equipped with Coex sealing vein, which creates excellent sealing and isolation during the curing process of powder coated profiles. IMPERIAL door profiles have thermal insulation at level UR = 2.2-2.3 W/(m2K), which classifies them in material group 2.1 according to DIN 4108.

Due to the parameters: profile width 65 mm (window and door outer frames, pillars and door wings), window sash width 74 mm and wall thickness 1.7 ÷ 2.0 mm, a stiff and static profile was achieved. It allows constructing doors at maximum dimensions of the door leaf: width 1300 mm with a maximum height of 2200 mm, width 1200 mm with a maximum height of 2400 mm. The Imperial system is very modern and versatile thanks to fastening fillings system from 4 to 51 mm (it allows outside glazing), use of branded fitting solutions and wide range of thresholds. Another advantage is the possibility of proper adjustment of a wing to window (several types of window frames and wings) and selection of wing depending on window fitting – there are wings designated for ALU fitting (EURO standard) as well as PVC window fittings.
